Having worked in the San Jose postoffice for about four or five years a long time ago as a Mail Handler I once submitted an idea to them about getting the mail which was
dumped out from mail sacks to a conveyor belt and then taken to the clerks at some distance who knew the scheme of the various zones. This was done by first taking the mail off the belt and then placed into trays which were then placed on the top of a cart. After stacking a reasonable amount of trays on top of each other, the cart was wheeled to various clerks who were processing the letters. My idea was to just place the letters into something shaped like a football which could be opened and shut and using the idea of fluid dynamics have the football shaped containers "flowed" to funnels in front of each clerk processing the letters. The funnels could be opened at desired times to drop the letter containers in front of separate clerks who could open up the "footballs", take a handful and start their job of placing the letters into the correct pidgeon holes.
Probably the post office now has their own system. My idea was naturally rejected.
But are there any worthwhile comments on this Rube Goldberg idea at this point in time?
